Description
Big airports such as Noi Bai and Tan Son Nhat fuel aircraft through fuel farms, pipelines and hydrant pits. Pump houses, filter vessels and dispenser trucks all sit on that network. Every flange, filter lid and coupling has to seal and stay sealed. The Snap-on TER175LC torque wrench gives fuel crews a dial in N·m and ft-lb, plus a lamp that flashes at the target.
Jet noise and a light cue
On the apron, engines and ground power units drown out almost any click. Crews also wear ear defenders, so sound cues fail. Snap-on fits a lamp to its Signal models, and it flashes once the bolt reaches the targeted torque. Thus the Snap-on TER175LC torque wrench lets the technician watch the flange and stop on the flash.

Snap-on lists the TER175L in its Combination US/Newton Meter Reading/Precise 1% Accuracy table. The catalog adds that a C at the end of the stock number orders the certificate of calibration model. So the TER175LC is that certified version, which fits the Lost in HCM title.

So use the system maker’s values, and work under your site’s permit and hazardous area procedures.
The lamp and fuel vapor
The source does not say whether the TER175LC lamp carries any rating for fuel vapor zones. So treat it as ordinary electrical gear, and follow your site’s gas test and permit steps.
Precise 1% on a 230 N·m dial
Lost in HCM files this wrench under Combination US/Newton Meter Reading/Precise 1% Accuracy. Snap-on keeps Precise wrenches within 1% of reading from 20% of full scale to full scale. For the TER175LC, the band starts at 46 N·m, or 35 ft-lb.
Fuel film, sun and the TER175LC
Jet fuel leaves a thin film that collects dust and grit. So wipe the wrench dry after each job, and return it to its PBR5 case. Keep it out of hot vehicle cabs too, because Snap-on rates its dial wrenches for 0 to 100 °F. Keep it off rusted or seized fasteners, since Snap-on says not to use a Torqometer to break them loose. Then schedule outside recalibration on your maintenance cycle.
